I grabbed this image of Albireo
a couple of nights ago:
The bright orange star has a surface temperature of about 4,500K and the blue one a surface temperature a little over 10,000K, hence the beautiful colour contrast between the two of them. For reference the Sun has a surface temperature a little under 6,000K.
Albireo should be easy to find in the night sky right now so long as you don't live way down in the Southern hemisphere or in a city. Have a look to the east around midnight and see if you can find the constellation of Cygnus, the Swan, as shown on the star chart here
. The same chart also shows Albireo (near the bottom). To the naked eye it looks like a single fairly unremarkable star.
